Protect your endpoints before traffic scales Try playground demo
Layer 1: verification
Enable Turnstile for forms exposed on public pages.
Require verification for suspicious or high-volume traffic patterns.
Keep fallback UX clear for legitimate users who fail a challenge.
Layer 2: endpoint controls
Set plan-aware limits and reject overage conditions gracefully.
Review per-form traffic patterns to spot abuse early.
Use webhooks to alert your team when unusual spikes occur.
Operational playbook
Keep a response template ready for temporary abuse incidents.
Audit form exposure across old pages and stale embeds.
Revisit rules whenever launch campaigns increase traffic.
Frequently asked questions
Is Turnstile required on every form?
Not always, but it is strongly recommended for public forms that receive unauthenticated traffic.
Can I still use webhooks when anti-spam controls are enabled?
Yes. Anti-spam checks and webhook delivery work together in the same submission flow.
